Start by heating olive oil in a large skillet over medium heat. If you're opting for bacon, now's the time to cook it until it's crispy and golden brown. Once done, set it aside on a paper towel-lined plate.
In the same skillet, add the diced potatoes. Spread them out in an even layer and let them cook for about 5-7 minutes, or until they start to brown. Stir occasionally to ensure even cooking.
Once the potatoes are nicely browned, add the chopped onion and minced garlic to the skillet. Sauté everything together until the onions are soft and translucent, and the garlic is fragrant.
Now, it's time to add the star of the show –the kale! Toss in the chopped kale and stir it into the potato mixture. Let it cook down for a few minutes until it wilts and becomes tender. This not only adds a vibrant pop of color but also loads of nutrients to the dish. Season everything generously with salt, pepper, and a pinch of paprika if you're looking to add a hint of smokiness. For a touch of acidity, a splash of apple cider vinegar can work wonders, but feel free to skip it if you prefer.
Once everything is well combined and cooked to perfection, it's time to reintroduce the crispy bacon back into the skillet. Give it all a final stir, allowing the flavors to meld together.
Serve your kale and potato hash hot off the skillet, garnished with extra crispy bacon if desired. This dish pairs beautifully with a fried egg on top or as a side to your favorite protein.
